ã€China Aluminum Industry Net】 Aluminum is one of the non-ferrous metals in the metal category. Due to its wide application, it is introduced separately as follows: There are two commonly used aluminum profiles and die-cast aluminum alloys. Among them, aluminum ingots with purity as high as 92% or more are used as the main raw materials, and metal elements such as carbon, magnesium, silicon, and sulfur, which increase strength, hardness, and wear resistance, are added to form various alloys.
Aluminum profiles such as screens, aluminum windows, showcases and so on. It is an extrusion molding process in which raw materials, such as aluminum ingots, are melted in a melting furnace and extruded through an extruder to form a mold. It can also extrude various sections of different profiles. The main performance of the strength, hardness, wear resistance according to national standards GB6063. The advantages are: light weight of only 2.8, no rust, rapid design changes, low mold investment, and longitudinal elongation of up to 10 meters. The appearance of aluminum profiles is bright and matt. The treatment process uses anodizing, and the surface treatment oxide film reaches 0.12m/m thickness. The wall thickness of aluminum profiles is selected according to the optimization of product design. The thicker the better the market is, the more the design of the cross-section structure is required. It can be uneven in 0.5~5mm. The layman believes that the thicker and tougher he is, he is actually wrong.
Aluminum surface quality also has more difficult to overcome the defects: warping, deformation, black lines, bumps and white lines. Designers with higher levels of design and mold design and production process are reasonable, which can avoid the above defects is not obvious. Inspection defects should be carried out according to the inspection methods prescribed by the State, that is, 40 to 50 cm in line of sight to identify defects.
Aluminium profiles are used in a wide range of furniture: screen skeletons, various suspension beams, table legs, trim strips, pull handles, cabling troughs and covers, chair tubes, etc., which can be designed and used in ever-changing designs!
Although aluminum profiles have many advantages, they are also unsatisfactory:
Unoxidized aluminum materials tend to “rust†and cause performance degradation. The longitudinal strength is not as good as that of iron products. The wear resistance of the surface oxide layer is less scratching than the plating layer. The cost is higher and the cost of the iron products is higher. About 3 to 4 times.
